QR Codes 2D barcode are square bar codes. QR codes have been in use since 1994. Originally used to track products in warehouses, QR codes were designed to replace traditional (1D bar codes). Traditional bar codes just represent numbers, which can be looked up in a database and translated into something meaningful. QR, or “Quick Response” bar codes were designed to contain the meaningful info right in the bar code.
